Radio reports indicated firefighters observed heavy smoke as they approached the structure.

According to fire officials, one person was taken to Alegent Creighton Health Lakeside Hospital in serious condition for treatment of smoke inhalation.

No other injuries were reported, but crews were able to rescue a cat from the building.

Authorities believe the fire started on the first floor, along the exterior of the structure.

The state fire marshal has been called in to investigate.

A fire at this apartment complex in 2012 displaced about 30 residents. About three months later, another 30 were displaced due to another fire. Both fires were blamed on careless cigarette smoking behaviors.

Last Tuesday, the apartments announced renovations and safety features, including extra sprinklers, as well as the decision to go smoke-free.
